본 고안은 캔드 펌프 모터의 슬리브 베어링 지지구조에 관한 것으로, 특히 슬리브 베어링을 지지하는 엔드실드에 홈을 형성하여 별도의 부싱없이 슬리브 베어링을 직접 지지하게 함으로써 제조원가를 절감할 수 있도록 한 캔드 펌프 모터의 슬리브 베어링 지지구조에 관한 것이다.The present invention relates to a sleeve bearing support structure of a canned pump motor. In particular, the canned pump motor has a groove in the end shield supporting the sleeve bearing to directly support the sleeve bearing without a separate bushing, thereby reducing the manufacturing cost. A sleeve bearing support structure.
일반적인 캔드 펌프 모터는 제 1 도에 도시한 바와같이 펌프케이싱(1)과 모터케이싱(2)을 서로 연통되게 결합하여 모터케이싱(2)의 내주면에는 고정자(3)를 고정설치하고 상기 펌프케이싱(1)과 모터케이싱(2)의 연결부에 설치된 엔드실드(4)와 모터케이싱(2)의 후단측 내면에 형성된 원형돌출부(5) 사이에 회전자(6)가 결합된 회전자축(7)을 슬리브베이링(8)(8')으로 지지하여 설치한 구성으로 되어 있다.In general can pump motor, as shown in FIG. 1, the pump casing 1 and the motor casing 2 are connected to each other so that the stator 3 is fixed to the inner circumferential surface of the motor casing 2 and the pump casing ( 1) and the rotor shaft (7) in which the rotor (6) is coupled between the end shield (4) provided at the connecting portion of the motor casing (2) and the circular protrusion (5) formed at the inner end side of the motor casing (2). It is the structure supported by the sleeve bay ring 8 and 8 ', and installed.
또한 상기 슬리브베이링(8)은 그 베어링(8)의 유동을 방지하기 위해 황동재질의 부싱(9)을 사용하며 그 부싱(9)은 엔드실드(4)의 내경에 압입되어 있다.The sleeve bearing 8 also uses a bushing 9 made of brass to prevent the bearing 8 from flowing, the bushing 9 being pressed into the inner diameter of the end shield 4.
일반적으로 슬리브 베이링은 제품구조상 물과 직접적인 관련이 없으므로 소결베어링 등을 사용하고 있으나 캔드 펌프는 소음을 감소하기 위하여 미케니컬시일(Mechanical seal)을 사용하지 않으므로 캔드 펌프 모터의 내부로 물이 유입된다. 이에따라 슬리브베어링은 내부식 재질인 세라믹 등을 사용해야 한다.In general, sleeve bearings use sintered bearings because they are not directly related to water, but can pumps do not use mechanical seals to reduce noise, so water flows into the can pump motor. do. Accordingly, sleeve bearings should be made of ceramics, which are corrosion-resistant materials.
한편, 모터 내부에 유입된 물은 슬리브베어링(8)과 회전자축(7)과의 마찰을 감소시키는 윤활작용을 하며, 모터 내부에 유입된 물이 권선(10)에 침투하여 절연파괴가 일어나는 것을 방지하기 위해 스테이트캔(11)과, 오링(12)을 사용하고 있다.On the other hand, the water introduced into the motor is lubricating action to reduce the friction between the sleeve bearing 8 and the rotor shaft (7), and the water introduced into the motor penetrates the winding (10) to cause the breakdown In order to prevent this, the state can 11 and the O-ring 12 are used.
그리고 캔드 펌프 모터 내부로의 물 유통은 제 2 도에서 보는 바와같이 엔드실드(4)와 황동부싱(9)의 접촉부에 형성된 틈(9a) 사이로 이루어지게 되어 있다.Water flow into the can pump motor is made between the gap 9a formed in the contact portion of the end shield 4 and the brass bushing 9 as shown in FIG.
도면에서 미설명 부호 13은 임펠러, 14는 스러스트베어링을 각각 보인 것이다.In the drawings, reference numeral 13 denotes an impeller, and 14 denotes a thrust bearing.
이러한 종래의 캔드 펌프 모터는 고정자(3)와 회전자(6)에 전원을 연결하면, 고정자(3)와 회전자(6)에 의해 회전축(7)이 회전하고 이에따라 임펠러(13)가 회전하여 펌핑작동을 하게 되어 있다.In the conventional can pump motor, when the power source is connected to the stator 3 and the rotor 6, the rotating shaft 7 is rotated by the stator 3 and the rotor 6, and the impeller 13 rotates accordingly. Pumping operation is made.
이러한 펌핑작동에 따라 펌핑유체(물)가 상기 엔드실드(4)와 황동부싱(9)의 틈새를 통해 펌프케이싱(1)과 모터케이싱(2)내의 캔(11) 내부 사이에서 순환되면서 윤활작용을 하게되어 원활한 회전이 가능하게 되는 것이다.According to this pumping operation, the pumping fluid (water) is circulated between the pump casing 1 and the inside of the can 11 in the motor casing 2 through the gap between the end shield 4 and the brass bushing 9. It will be able to rotate smoothly.
그러나, 종래의 캔드 펌프 모터는 엔드실드(4)의 내경과 슬리브베어링(8)의 외경 사이에 부싱(9)을 사용하므로 원가상승요인을 초래하고 더우기, 모터케이싱(2)의 회전자부를 통해 물이 유입/유출되어야 하므로 물이 접촉되는 부위의 사용재질이 물에 의해 부식되지 않는 것으로 사용해야 한다. 이러한 이유로 인하여 슬리브베어링(8)을 지지해주는 부싱(9)은 황동을 사용해야 한다.However, the conventional can pump motor uses the bushing 9 between the inner diameter of the end shield 4 and the outer diameter of the sleeve bearing 8, resulting in a cost increase factor and, moreover, through the rotor portion of the motor casing 2. Since water must be inflow / outflow, it should be used so that the material used in the water contact area is not corroded by water. For this reason, the bushing 9 supporting the sleeve bearing 8 should use brass.
또한, 캔드 펌프 모터 내부로의 물 유통을 목적으로 형성한 엔드실드(4)와 부싱(9)의 틈 사이로 이물질(예를 들어 작은 돌멩이 등)들이 물과 함께 유입되어 간혹, 고정자(3)와 회전자(6) 사이 또는 베어링(8)과 축(7)사이에 끼어 구속되는 결함이 있었다.In addition, foreign matter (for example, small stones, etc.) flows into the gap between the end shield 4 and the bushing 9 formed for the purpose of distributing water into the can pump motor, and occasionally, the stator 3 There was a defect that was pinched between the rotors 6 or between the bearing 8 and the shaft 7.
따라서, 본 고안은 상기한 바와같은 종래 캔드 펌프 모터의 결함을 해소하고, 제조원가를 절감할 수 있도록 엔드실드에 U자형 단면의 홈을 형성함과 함께 그 홈에 수개의 윤활제(물)유통홈을 형성하여 상기 엔드실드의 내경부위에 별도의 부싱 사용없이 엔드실드와 슬리브 베어링이 직접 접촉되게 한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention forms a groove having a U-shaped cross section in the end shield and eliminates the defect of the conventional can pump motor as described above, and reduces the manufacturing cost. Formed so that the end shield and the sleeve bearing is in direct contact with the inner diameter portion of the end shield without a separate bushing as described in detail with reference to the accompanying drawings.
본 고안에 의한 엔드실드가 적용된 캔드 펌프 모터는 제 3 도 및 제 4 도에 도시한 바와같이 펌프케이싱(1)과 모터케이싱(2)을 서로 연동되게 설치하여 상기 모터케이싱(2)의 내주면에는 고정자(3)를 고정설치하고, 상기 펌프케이싱(1)과 모터케이싱(2)의 연결부에 설치된 엔드실드(20)와 모터케이싱(2)의 후단측 내면에 형성된 원형돌출부(5)사이에 회전자(6)가 결합된 회전자축(7)을 슬리브베어링(8)(8')으로 지지하여 설치한 것에 있어서, 상기 엔드실드(20)에 U자형 단면의 홈(20a)을 형성하여 상기 엔드실드(20)가 슬리브베어링(8)과 직접 접촉되도록 함으로써 엔드실드(20)의 내경부위에 별도의 황동부싱을 사용하지 않음으로 인한 제조원가를 절감할 수 있도록 구성한 것이다.In the canned pump motor to which the end shield according to the present invention is applied, the pump casing 1 and the motor casing 2 are interlocked with each other, as shown in FIGS. The stator 3 is fixed and installed between the end shield 20 provided at the connecting portion of the pump casing 1 and the motor casing 2 and the circular protrusion 5 formed on the inner surface of the rear end side of the motor casing 2. In the case in which the rotor shaft 7 coupled with the electrons 6 is supported by the sleeve bearings 8 and 8 ', the groove 20a having a U-shaped cross section is formed in the end shield 20. The shield 20 is configured to directly reduce the manufacturing cost due to not using a separate brass bushing on the inner diameter of the end shield 20 by direct contact with the sleeve bearing (8).
또한, 상기 엔드실드(20)의 U자형 단면의 홈(20a) 부위에 수개의 윤활제(물)유통홈(21)을 형성하여 펌프모터 내부로의 윤활제(물)유통이 보다 잘 이루어지도록 되어 있으며, 이 유통되는 물은 슬리브베이렁(8)과 회전자축(7)과의 윤활작용을 함과 동시에 캔드펌프 모터의 온도상승 저감 작용도 겸하게 되는 것이다.In addition, a plurality of lubricant (water) flow grooves 21 are formed in the groove 20a of the U-shaped cross section of the end shield 20 so that the lubricant (water) flow into the pump motor is made better. This circulated water is lubricated between the sleeve base 8 and the rotor shaft 7, and also serves to reduce the temperature rise of the canned pump motor.
한편, 제 5a, b 도는 본 고안에 의한 엔드실드의 실시예를 보이는 평면도 및 이의 단면도로서 이에 도시한 바와같이 상기 엔드실드(20)의 윤활제유통홈(21)을 통해 물과 함께 캔드 펌프 모터 내부로 유입되는 이물질들의 침입을 방지하기 위해 상기 엔드실드(20)의 U자형 단면의 홈(20a)에 필터(30)를 슬라이딩 접촉되게 삽입하거나 압입하여 구성한 것이다.On the other hand, Figure 5a, b is a plan view showing an embodiment of the end shield according to the present invention and a cross-sectional view thereof as shown in this through the lubricant through the groove 21 of the end shield 20 with the water inside the can pump motor In order to prevent the ingress of foreign substances introduced into the filter 20 is inserted into the groove (20a) of the U-shaped cross section of the end shield 20 to be in sliding contact or is configured by pressing.
또한, 상기 필터(30)의 이탈을 방지하기 위해 엔드실드(20)의 일측부에 1m∼5m정도의 스티킹(sticking) 처리를 하도록 되어 있다.In addition, in order to prevent separation of the filter 30, a sticking treatment of about 1 m to 5 m is applied to one side of the end shield 20.
도면에서 종래 구성과 동일한 부분에 대해서는 동일 부호로 표시하였다.In the drawings, the same parts as in the conventional construction are denoted by the same reference numerals.
이와 같이 된 본 고안의 펌핑 작동 과정을 종래와 동일하나 황동부싱이 제거되므로 조립이 간편용이해지고 원가를 절감할 수 있을 뿐만 아니라 필터를 사용함으로써 이물질의 침입을 방지할 수 있는 특징이 있다.The pumping operation process of the present invention as described above is the same as the conventional one, but because the brass bushing is removed, as well as easy to assemble and reduce the cost, there is a feature that can prevent the intrusion of foreign matter by using a filter.
이상에서 설명한 바와같이 본 고안에 의한 엔드실드가 적용된 캔드 펌프 모터는 엔드실드(20)에 U자형 단면의 홈(20a)을 형성하여 그 엔드실드(20)와 슬리브베어링(8)이 직접 접촉되게 함으로써 고가의 황동부싱이 제거되므로 원가를 절감할 수 있을 뿐만 아니라 조립이 간편, 용이해지는 효과가 있다.As described above, the canned pump motor to which the end shield according to the present invention is applied forms a groove 20a having a U-shaped cross section in the end shield 20 such that the end shield 20 and the sleeve bearing 8 are in direct contact with each other. By removing the expensive brass bushing can not only reduce the cost, but also easy, easy assembly.
또한, 상기 엔드실드(20)의 U자형 단면의 홈(20a)에 필터(30)를 사용함으로써 윤활제유통홈(21)을 통해 물과 함께 캔드 펌프 모터 내부로 유입되는 이물질들의 침입을 방지할 수 있으며 이에 따라 축 및 베어링의 마모를 방지할 수 있는 효과를 기대할 수 있다.In addition, by using the filter 30 in the groove (20a) of the U-shaped cross-section of the end shield 20 can prevent the intrusion of foreign substances introduced into the can pump motor with water through the lubricant distribution groove (21). As a result, the effect of preventing the abrasion of the shaft and the bearing can be expected.
